According to the Center for Biological Diversity, Wildlife Services has long been secretive for a reason: Its actions are incredibly, unacceptably and illegally brutal and inhumane to animals, from familiar wildlife to endangered species — and even people's pets.

"This agency has been killing as many as 3 million native animals every year — including coyotes, bears, beavers, wolves, otters, foxes, prairie dogs, mountain lions, birds and other animals — without any oversight, accountability or requirement to disclose its activities to the public. The agency contributed to the decline of gray wolves, Mexican wolves, black-footed ferrets, black-tailed prairie dogs, and other imperiled species during the first half of the 1900s, and continues to impede their recovery today."
